Weather in Cancun In August – At a Glance

You’re probably curious about what the weather is like in Cancun in August. The answer is that it’s a mixed bag! Cancun weather can be hot and sunny one day, or rainy and overcast the next.

Sometimes the weather even changes from hour to hour. Average daily temperatures are typically the highest they are all year, hovering between the high 80s to mid 90s.

Given the region’s tropical climate, it’s difficult to predict the weather in Cancun 100 percent of the time. It’s helpful to keep an eye on the weather for about a week leading up to your scheduled trip, especially during the hurricane season.

However, don’t base your decision to travel to Cancun solely on the weather. It can go from sunny to overcast, and dry to rainy in a matter of hours, but rarely gets

The hottest period of the year is late spring to early fall (the hurricane season), and the coolest period of the year is winter (December to March).

Does it rain in Cancun in August?

Rain is likely a topic that crosses your mind when planning a trip to the Caribbean.

The bad news is that due to Cancun’s subtropical climate and location on the Caribbean Sea, it’s very prone to light rain showers or surprise bursts of cloud cover and heavy rain.

The good news is that it rarely storms bad enough to cause concern.

The rainy season in Cancun is from May to October, which is nearly the entire duration of the Atlantic Hurricane season.

The average rainfall in August is 85mm with 21.3 total days of rain, making it the third wettest month of the year.

☂️ Does it rain all day in Cancun in August?

The short answer is no. Even though August is one of the wettest months of the year for Cancun, it will rarely rain all day with no periods of sunshine in between.

Now, if you do get some rain during your Cancun vacation –  and you likely will –  don’t worry. Rain storms typically pass quickly.

If for some reason it doesn’t, there are plenty of fun indoor activities you can enjoy until it does. Plus, watching and listening to a mild thunderstorm or rain shower from the comfort of your resort can be pretty relaxing!

☂️ Best things to do in Cancun when it rains 

Cancun is home to tons of boutique shops and shopping malls including the Las Isla Paradise Experience, the Puerto Cancun Marina Town Center, and the Las Plazas Outlet Cancun.

Many of these shopping malls offer affordable deals, upscale retailers, movie theaters, and restaurants. The outlet mall is even home to a movie theater and a casino!

If you’re a history buff, perhaps a museum is more your forté. There are plenty of museums located in and around Cancun that are perfect for solo travelers and families alike.

If you’re traveling with kids, the Cancun Wax Museum or the Ripley’s Believe It or Not! are great options.

For solo travelers or couples, the Museo Hacienda Tequila and the Mayan Museum of Cancun are both educational and fun. And yes, you can actually taste mezcal and tequila varieties at the tequila museum!

Is it hot in Cancun in August?

Cancun is hot year-round, so it may come as no surprise that it is hot in August too! In fact, it’s one of the hottest months of the year.

You may get some slight relief at night after the sun goes down (not much, however), after a rainstorm, or if you visit during the winter months.

If you’re wondering if the temperatures might be too hot for you in August, it’s difficult to say since this is based on personal limits and preferences.

If you’re someone who is very sensitive to heat and humidity, it might be best to visit during a cooler month or fill your itinerary with indoor activities.

Still, regardless of when you visit Cancun, be prepared to sweat just a little if you plan to spend time outdoors.

Is it very humid in Cancun in August?

It’s nearly impossible to outrun the humidity no matter what time of year you visit. Due to its vast jungle landscape and location on the water, it’s the perfect storm for high levels of humidity.

The average relative humidity in Cancun in August is between 70 and 90 percent. This means that it will feel even hotter than the actual air temperature.

Because of this, it’s important to wear plenty of sunscreen, seek shade when you need it, and stay hydrated by bringing a reusable water bottle.

Thankfully, you can usually find a nice cool breeze the closer to the coastline you get, and sometimes there is a nice breeze at night after the sun goes down.

Are there hurricanes in Cancun in August?

There’s always a chance of experiencing a hurricane in the Caribbean during the Atlantic hurricane season.

Some regions in the Caribbean have a higher likelihood of a hurricane making landfall, but thankfully, Cancun is not one of them.

In fact, only two hurricanes have made landfall in Cancun in nearly 40 years.

The first was Hurricane Gilbert in 1998, and the second was Hurricane Wilma in 2005. Although both storms caused some serious structural damage and flooding, Cancun has since built numerous storm shelters within hotels and resorts along the Hotel Zone.

In fact, most properties have some sort of shelter in place in the rare event a hurricane makes landfall unexpectedly.

🌀 When is Hurricane Season in Cancun?

Known as the Atlantic Hurricane Season, its official period runs from June 1 to November 30. This doesn’t mean that hurricanes make landfall every month of this period, however.

The months with the highest likelihood of a hurricane forming are actually August, September, and October.

Even still, hurricanes in Cancun are very still something to be mindful of when planning your vacation. Meteorologists can typically predict a hurricane making landfall 3 to 5 days in advance.

Monitor local weather patterns about a week or so before your trip, but don’t base your entire decision on going to Cancun on the chance of a hurricane.

🌀 Is Cancun safe during hurricane season?

Yes, Cancun is absolutely safe during the hurricane season. Because of the peninsula that protects the region surrounding Cancun, it’s actually very rare that a hurricane of any form makes landfall.

Scientifically, only the eye of the hurricane (the area close to the center of the storm) can do the most damage. Therefore, if it doesn’t make landfall, the level of damage and danger factors are far less severe.

Sea water temperature in Cancun in August

The Caribbean Sea is warm year-round, making it a prime spot to enjoy water activities and beach days.

The average water temperature in Cancun in August is 85 degrees Fahrenheit, which is above standard sea temperatures of 77 degrees Fahrenheit and 84 degrees Fahrenheit.

🌊 How warm is the water in Cancun in August?

The water is the warmest between July and October, meaning August brings some of the warmest water temperatures of the year.

It’s one of the best months for swimming, snorkeling, and diving without the need for a wetsuit or much discomfort.

🌊 Sea visibility in Cancun in August 

Sea visibility lessens during the hurricane season as frequent rain and less sunlight can stir up particles in the ocean.

If you’re a diver, especially a deep sea diver, the dullness of the water could hinder your ability to see clearly.

During the summer months, there’s usually less than a 30 percent possibility of sunlight during the day which lowers sea visibility, even in shallow waters and coral reefs.

If you happen to snorkel or dive on a clear and sunny day (which August will still have some of!), the water visibility should be perfect for viewing wildlife.

You can get up close and personal with turtles, sting rays, different species of fish, and even whale sharks if it’s the right time of year.

Sargassum Seaweed In Cancun in August

Unfortunately, during the summer months of July and August, sargassum levels are at their peak. The seaweed washes up on the shores in piles on many beaches throughout the Yucatan Peninsula.

Marine biologists don’t know exactly where it comes from or why it’s become a problem in recent years.

However, what they do know is that it decomposes in the sun and heat once it reaches the shore and causes an unpleasant sight and a foul smell.

There is no foolproof method to prevent the sargassum from washing up on the shores. What you can do is look for hotels and resorts that have a system for removing the seaweed from their property’s beaches, or research which beaches in the region might experience fewer levels.

If all else fails, you can always just enjoy a nice swimming pool at your hotel or Airbnb property to beat the heat.

Events in Cancun in August

There is always something fun to experience in Cancun no matter the time of year. August welcomes a few different must-see cultural events that are detailed below:

The Assumption of the Virgin Mary

Celebrated on August 15th, the Assumption of the Virgin Mary or the “Feast of Assumption” is a Catholic holiday and feast held in churches throughout Mexico.

The holiday celebrates Jesus’s mother Mary’s arrival in heaven. Those who celebrate it believe that after Mary died, her body reunited with her soul rather than going through the normal process of decomposition.

Many towns and cities throughout Mexico hold processions and parades and decorate churches and statues in her image with flowers and banners.

The holiday is a religious observance and not a public holiday, so many businesses still operate as usual.

🕺🏼 ZoukMX

If you’re looking to party during your vacation to Cancun, you’ll want to attend the ZoukMX in Playa del Carmen.

This 30-day Caribbean music festival is one of the biggest and longest celebrations in the Cancun area. It includes everything from workshops and dance lessons to concerts and of course, a lot of parties.

Professional Zouk dancers descend on the Yucatan Peninsula to teach classes, workout sessions, and parties with DJs. It’s the only event like it in North America!

Pros of Visiting Cancun in August

👍🏼 Two words: whale sharks! August is the peak season for whale shark migratory patterns, so the likelihood of getting up close and personal with them during a guided tour is much higher.

👍🏼 Even though it’s hurricane season, the likelihood of the eye of a hurricane making landfall is very rare. Aside from some daily showers, you should still enjoy plenty of sunny and warm days which will be perfect for exploring.

👍🏼 The water temperature is at its warmest all year making it a prime time to enjoy swimming, snorkeling, boating, and diving without being uncomfortable.

Cons of Visiting Cancun in August

👎🏼 Even though the summer months are considered the low season, prices for hotels and resorts are still high-end. This is because children are still out of school for the summer break, and many families naturally choose Cancun as their vacation destination.

👎🏼 School is still out for the summer and families from the U.S., Europe, and South America choose Cancun as their vacation destination. This not only drives up prices due to supply and demand but makes for more crowded beaches and popular attraction sites.

👎🏼 If you’re someone who is sensitive to heat and humidity, August may not be the best time to visit Cancun. If you’re up for braving the sticky heat, you will definitely want to stay hydrated and spend equal time outdoors and indoors in air conditioning.

👎🏼 Sargassum seaweed. July and August are two of the worst months for the levels of seaweed that wash up on some of the beaches in the Yucatan Peninsula. While the seaweed itself isn’t a huge danger to humans, it looks awful and smells even worse. If you want to avoid it as much as possible, check with your hotel or resort to see which beaches are less prone to it. If you plan to spend a lot of time at your resort, ask if they take measures to clean up the beaches on their properties. 

Things to Do in Cancun in August

👉🏼 Swim with whale sharks

Whale sharks thrive in warm, tropical waters pretty much anywhere in the world. But the best time to see them depends on where in the world you’re going and what time of year you go.

In Cancun, the height of the whale shark season is June to September, with the best months to see them being July and August.

The best way to experience the biggest fish in the sea is to book a professionally guided tour. There are plenty of tours offered out of Playa del Carmen, Riviera Maya, Cancun, Cozumel, Tulum, and Isla Mujeres.

These tours give you an opportunity to safely interact with these majestic animals in their natural habitats during a half or full-day snorkeling tour.

👉🏼 Visit Chichen Itza

It’s not a trip to Cancun without a trip to Chichen Itza. These ancient Mayan ruins are among the most popular (if not the most popular) landmarks in Mexico.

This incredible archaeological site is a must-see and makes the perfect half or full-day trip from Cancun. It’s best to get there early in the morning as it can get very crowded, especially during the summer months.

You can take a rental car and explore the site on your own time, or book a guided tour. Exploring on your own is great if you’re short on time, but the guided tours really provide more insight into the role this pre-Columbian city played in Mayan Civilization.

👉🏼 Go on a day trip to Tulum 

Going on a day trip from Cancun to Tulum is one of the most popular activities among tourists.

A two-hour drive straight down the Mexican Federal Highway and you’ll find yourself in close proximity to dozens of beautiful cenotes, stunning beaches, and some of the best restaurants in the region.

A few of the most popular places to kick back and unwind include Akumal Beach, Playa Paraíso, Gran Cenote, and Cenote Calavera.

👉🏼 Try some of the great restaurants

Cancun is truly a foodie’s paradise. Due to the blend of cultures in the city, the cuisines available at its many bars and restaurants extend far beyond just Mexican food (though you can find plenty of that, too, of course!)

From tamales and chilaquiles to the freshest shrimp ceviche, the Cancun food scene is exploding with unforgettable dining experiences.

Aside from authentic Mexican food, you can also find many restaurants that serve Italian cuisine, Mediterranean cuisine, Indian cuisine, and Japanese cuisine. Both downtown Cancun and the hotel zone boast an incredible variety of cuisine.

Many four and five-star hotels and resorts in Cancun also regularly host Michelin and top-rated chefs for special dinners, live cooking shows, and seasonal residencies.

👉🏼 Go Snorkeling 

Cancun is home to some of the best snorkeling spots in the world.

From the ocean to freshwater cenotes, there are endless opportunities to explore coral reefs, underwater caves, mangrove canals, and hidden passageways.

The water temperature in August also makes snorkeling extremely enjoyable. Many species of wildlife make their homes in the Caribbean Sea or migrate through these waters, which makes August a great month to set your sights on them.

Tips For Visiting Cancun in August

📌 Pack comfortable walking shoes, sunscreen, glasses, lightweight clothing, breathable tops and bottoms, and plenty of beach wear!

📌 Mosquitos can be thick in certain terrains throughout the Yucatan Peninsula, so it’s best to bring insect repellent and reapply it before heading outdoors. Remember to wash it off before swimming in the ocean or in a cenote.

Keep mosquitos away!

📌 Bring a small amount of local money in cash (Mexican Pesos) with you. A good rule of thumb to follow is to bring 25 percent of the total cost of your trip in cash.

📌 It’s best to get the cash from your local bank prior to your vacation, or at a verified ATM in a tourist area once in Cancun.

📌 Only drink bottled water! The tap water in Cancun is not safe to drink and could make you very sick if ingested. Also, be careful of how vegetables and fruit are washed and whether or not the skin is still on raw fruits.

📌 Purchase travel insurance prior to leaving for your Cancun vacation. You never know what could happen, so it’s nice to have extra peace of mind knowing that certain incidents will be covered.
